... Abstract Improvement to the efficiency of pre-salt well delivery was achieved by implementing detailed planning with cross discipline teams who developed a complete vibration mitigation program that became indispensable in critical wells, such as the ones in Ultra Deep Water Pre-Salt...

... A study is presented of the potential capacity of pipeline vibration dampers (PVDs) to mitigate vortex induced vibration (VIV) for subsea pipeline spans. The study also makes evaluations for VIV fatigue damage reductions that could be accomplished by PVDs for the spans. While it is recognized...

... The jumpers are typically curved pieces used to connect manifold system to wells head. In the area, it is normally exposed to significant currents. So the jumpers are subject to vortex induced vibration (VIV). However, the experimental method for prediction of vortex induced vibration (VIV...

... Drilling (MWD), magnetic, vibration and underreamer position sensors can be added. A R&D project was established with incremental tests identifying root-cause failures/design issues before moving to the next stage. This iterative process ensured proper prototype manufacturing and minimised risk...

... quite a challenge. The lithology of the wells in block C-M-592, pore pressure profiles and the requirement for formation evaluation while drilling are challenges that needed to be addressed in the design and drilling of these wells. In addition, multiple bit trips, low ROP, and high drilling vibrations...

... section the ROP was lower than expected mainly due to high vibrations (axial, lateral and torsional) combined with hard and abrasive formations with intercalations of soft lithology. The consequences in a BHA (Bottom Hole Assembly) component can be seen in Fig 4, this uneven wear is a classic example...
